Zoom type of movement or speed of light effect

giorgiomartini

Hi there,

I have this sketch with some stars.

and i want them to move out of the screen in a "zoom motion blur" type of motion like this:

any idea how to go about it ? thanks !

This is the code :

    Star[] stararray = new Star[100];


    void setup(){
     // smooth();

    size (400,300);

    for (int i =0; i<stararray.length; i++){
      stararray[i] = new Star(random(width),random(height),2);
    }



    }

    void draw(){
    background(0);



    for(int i =0; i<stararray.length; i++){
    stararray[i].display();
    }

    for(int i =0; i<stararray.length; i++){
    stararray[i].move();
    }

    }

    class Star {

      //declare variables
      float s;
      float x;
      float y;

      //constructor
      Star(float x_,float y_,float s_) {

        s = s_;
        x = x_;
        y = y_;
      }

      //functions
      void display() {
        //noStroke();
        fill(255);
        ellipse(x, y, s, s);
      }
      // move
      void move(){
      x+=1;
      y+=1;

      // if x goes out of screen bring back on the oposite side
      if(x<0){
      x = width;
    }  
        if(x>width){
      x = 0;
      }
      // if y goes out of screen bring back on the oposite side
       if(y<0){
      y = height;
      }  
        if(y>height){
      y = 0;
      }


      }

    }
